The WebGL2RenderingContext.getInternalformatParameter() method of the WebGL 2 API returns information about implementation-dependent support for internal formats.
getInternalformatParameter(target, internalformat, pname)targetA GLenum specifying the target renderbuffer object. Possible values:
gl.RENDERBUFFERBuffer data storage for single images in a renderable internal format.
internalformatA GLenum specifying the internal format about which to retrieve information (must be a color-renderable, depth-renderable or stencil-renderable format).
pnameA GLenum specifying the type of information to query. Possible values:
gl.SAMPLESReturns an Int32Array containing sample counts supported for internalformat in descending order.
Depends on the requested information (as specified with pname). It is an Int32Array if pname is gl.SAMPLES.
const samples = gl.getInternalformatParameter(
gl.RENDERBUFFER,
gl.RGBA8,
gl.SAMPLES,
);
